driving up or down grades. The mode status will
be indicated on the digital display by a red LED
illuminating in the upper right corner of the
MODE button when selected.
Oil Level Display Mode (optional)
Select oil level display mode by pressing
simultaneously on the "
" and " " keys. A first
press will indicate the transmission oil level after
a two-minute wait if the following conditions are
met:
• The vehicle is parked;
• The engine is in slow idle;
• The transmission has reached it’s normal
operating temperature;
• Transmission is in NEUTRAL;
• The optional sender unit is present and
working.
A code will be displayed one digit at a time:
O L - O K (oil level is correct);
L O - 0 1 (one quart low);
L O - 0 2 (two quarts low);
H I - 0 1 (one quart high);
H I - 0 2 (two quart high).
Note: If one or more conditions are not met, an
error code will be displayed:
O L - 5 0 (engine RPM too low);
O L - 5 9 (engine RPM too high);
O L - 6 5 (transmission not at NEUTRAL);
O L - 7 0 (sump oil temperature too low);
O L - 7 9 (sump oil temperature too high);
O L - 8 9 (output shaft rotation);
O L - 9 5 (sender unit defective).
To exit, press either D, R, or N button.
Diagnostic Display Mode
Pressing a second time (or a first time if oil level
option not present) on the "
" and " " keys
simultaneously will select the diagnostic display
mode. Refer to the "Technical Information"
chapter for more information about the WT
diagnostic codes. To exit diagnostic display
mode, press either D, R, N button, or up and
down arrow keys at the same time.
Reverse (R)
Use this position to back-up the vehicle. Stop
completely before shifting from forward to
reverse or from reverse to forward. Touch the
reverse (R) button, ‘’R’’ will be displayed and the
reverse warning signal will be activated.
Neutral (N)
Use this position to start engine. Select neutral
(N) when checking vehicle accessories and for
extended periods of engine idle operation;
parking brake must then be applied. The push-
button shifter will automatically select neutral
when the master switch is turned ON.
Note: The automatic transmission does not
have a park (P) position. Select neutral (N) and
apply parking brake when the vehicle is left
unattended. A warning buzzer will sound if the
engine is stopped and the parking brake has not
been applied when foot pressure is removed
from the brake pedal.
Warning: Always apply parking brake before
leaving driver's seat.
Caution: Detroit Diesel engines should not be
idled for extended periods at "slow" idle. For
extended idling, engine should run at "fast" idle.
Caution: Do not allow your vehicle to "coast" in
neutral. This practice can result in transmission
damage. Also, no engine braking is available in
neutral.
Drive (D)
Use this position for all normal driving
conditions. After touching this pad, the vehicle
will start in first or second range and will
automatically upshift to a higher range as output
speed increases. As the vehicle slows down,
output speed decreases, the transmission
automatically downshifts to the correct range. If
a locked brake or a slick surface condition
should occur, the ECU (Electronic Control Unit)
will command converter operation (disconnect
lockup) and inhibit downshifts for a period of time
or until normal wheel speed has been restored.
